What is the energy released when three alpha particles combine to form 12C?

I need help on this question

Q3: The table shows two isotopes of potassium and two isotopes of calcium. Type of emission Mass of neutral atom / u Number of electrons Number of protons Number of neutrons Total mass/u Mass defect/ u Binding energy / J Mass of the electron = 0.000549 u Mass of the proton = 1.007276 u Mass of the neutron = 1.008665 u TI ***** LEG 39K Stable 38.96371 SE nda 42K ß decay a) Use data about potassium-42 to explain the concept of mass defect. 3000 41.9624 19 19 23 42.34797 0.38557 5.76 x 10-11 De RAP 39 Ca ßt decay 38.9707 440 **** ****** D 42 Ca stable 41.95863

What isotope is produced when Np-239 emits a beta particle?

Cobalt-60 undergoes beta minus decay. Determine the daughter nucleus and compare the calculated binding energy per nucleon of the parent and daughter nuclei. mass (Co-60) = 59.933817 u mass (daughter) = 59.930786 u

One of the fusion reactions that takes place as a star ages is called the triple alpha process. 3 42He → 126C Calculate the mass defect (in u) and the energy produced (in MeV) each time the reaction takes place.

The nucleus 158O has a half-life of 2.00 min. 198O has a half-life of about 0.500 min

Select each of the following that is a characteristic of alpha decay. The mass number of the nucleus that decays decreases by 4. O The radiation that is produced carries a negative charge. O The atomic number of the nucleus that decays increases. The chemical element of the nucleus that decays remains unchanged. O The mass number of the nucleus that decays remains unchanged. The mass number of the nucleus that decays decreases by 2. O The radiation that is produced carries a positive charge. The atomic number of the nucleus that decays decreases.

Determine the nucleus density (in kg/m³) of the following four isotopes. 4He (m= 4.00260325415 u) 40 Ar (m 39.9623831225 u) 179TI (m 178.99109 u) 232U (m 232.0371562 u)
